The CT181 Series is a general-purpose optocoupler featuring a phototransistor optically coupled to a gallium arsenide infrared-emitting diode, housed in a 4-lead Mini-Flat package. It offers high isolation of 3750 VRMS, a creepage distance of 5mm, and an operating temperature range of -55C to 110C. Available with multiple CTR selections, this series is suitable for applications such as DC-DC converters, programmable controllers, telecommunication equipment, and hybrid substrates requiring high-density mounting. The product is designed with a green package and is pending various regulatory approvals including UL, VDE, CQC, and IEC standards.
